While acting as an HTTP proxy, it protects your privacy by deleting (or faking) eight data elements, including the Cookie field and Referrer fields, from every request that your browser sends out to web servers on the Internet. It is the blocking of these data elements — not the blocking of sites or, as some would have you believe, the blocking of ads — that protects your privacy. Although the blocking of sites (or ads) does not enhance your online privacy, that capability is also included here because blocking content in which you're not interested can significantly reduce download times. In doing so, Surfer Protection Program does not modify the content of any web page. It simply disregards a request for content whose address matches any of the blocking rules that you have specified. Finally, shielding your online privacy on a single computer is not enough in a networked, multi-computer household. With Surfer Protection Program, all of your networked machines can direct their requests to a single copy of the software running on the computer that is connected to the Internet so that no one is at risk of being profiled.
